Application filed m 26, 1am. tlcriul m. scacca' v r State of Rhode Island, have invented certain new and useful Improvements in Shell-Rim Fasteners for Eyeglasses; and I do declare the following tube a fulhclear, and exact description of the-invention, such as Will :enahle others skilled in the art to which itappertains to malts and use the same.

, This invention relates to an improved eyeglass construction'and has part cular refer- .may be securely held in place without the metal lens holding rims.

One object of the invention is to so con struct the fasteners that the shellrims may be securely held in place and prevented from moving out of engagement with the metal lens holding rims.

Another object of the invention is to so construct this fastener that in addition to holding the shell rims in place, the fastener may also serve as means for preventing the lenses from havingrotary movement in the metal lens holding rims.

Another object oi the invention isito so construct this fastener that it may he mount--- ed upon the metal lens-holding rims and have firm engagement with the shell rims.

Another object of the invention is to so construct the fastener that itwill be cheap to produce and be easy to put in place.

- 'This invention isillustrated in the accompanying drawings, wherein:

Figure 1 is a View showing a pair oi eyeglasses provided. with shell rims held in ,place by means of the improved fasteners,

showing the modified construction of sleeve i similar to'Fig. show- Fig. 1.3 is a view similar to Fig. 3 show:

ing the fastener of Fig. 12 in use.

The glasses are provided withthe usual bridge or nose-'piece' 1 which connects'the metal rims :2 which rims Wlll have the usual construction and will hc provided with oars 3 through which will pass a. fastener screw i to releasahlyconnect the ears and'serve as means for mounting the hows 5 for hold ing the glasses in place. The metal rim 2 is provided with a groove 6 as shown-in Fig. l

3 to receive the edge portion of the lens 7 and will thus obtain a firm gri upon the lens so that the lens will be he (1 in place. While this will serve to hold the lens in place, a lens will often he slightl loose in the frame and may rotate. In'or or to prevent rotation oi the lens and to further ro vide means to holding a. shell rim Sin p ace,

the improved fastener which will now be described has been provided.

lo. the hccompanying illustration, fastenors having modified constructions have been shown. lln the form shownin" Fi s. 2,

. 3 and 4:, the device is provided 'with a s eeve 9 which may he split longitudinally and is placed about the rim 2 and bent to provide flanges 9 which extend into the groove 6 as shown in Fig. 3 thus securely connecting the sleeve with the rim 2. A pin ldextends from the sleeve 9 and will pass through an opening formed in the shell rim; the sleeve has been put iii-place and. the stem passed through the opening of the shell rim, the stern will he cut off and riveted thus providing a head 12. The end portion of the shell rim 8 is cut from. its inner face to provide a pocket 13 intowhich the sleeve 9 After seat 1+1- tor thesleeve of each fastener as shown in Fig. 2. Therefore, when the iastcners are in place and the shell rims secured by the two fasteners, the shell-rim movement will be securely held in place and the lens will be held against rotary the sleeve fitting into the-seat 14.

In the form shown in Fig. 5, the sleeve 9 may be split longitudinally or maybe placed about the rim 2 and crimped longitudinally [to provide a tongue extension fitting into the i The stem 10 will be omitted in groove 6. this form, and in place of a stem, :1 rivet 15 will be provided, the rivet having a split free end portion thus providing fingers 16 which will spread and clench the rivet in place, with ;the rivet extending through an opening formed in the shell rim 8 and into an opening formed in thesleeve 9 and registering with the opening of the shell rim.

In the form shown in Fig. 6, the sleeve will be formed as shown and previously described in connection with Figs. 2 and 5,

' and this sleeve will be provided with a registering openings formed in the shell rim.

' ings formed in the shell ri tions of the shell rim beingcut to provide After being passed through openings inv the shell rim, the end portions of the wire will be drawn together and twisted thus firmly holding the end portions of the shell rim in place. If desired, the end portions of the shell rim may be provided with grooves to receive the end portions of the wire 18.

In the form disclosed in Figs. 8 and 9, the sleeve is of the type crimped longitudinally to fit into the groove of the lens holding rim 2 and this sleeve is provided with a longitudinally extending rib 19 which fits into a longitudinally extending groove or seat 20 formed in the shell rim 8. This rib is provided with an opening at a. point intermediate its length and a pin 21 passes through this opening and through rlg'gistering openpockets 22 which will be positioned heads formed by riveting the end yportions of the pin 21. 1

In the form shown in Figs. 10 and 11, the

" structure is similar to the forms shown in Figs. 2, 3 and 4, in that the sleeve is provided with a stem 23 which extends through an opening formed in the shell rim but .in this form, the stem 23 is split longitudinally thus providing arms 24 which will be bent about the shell rim transversely of the same and clamped into tight engagement with the shell rim. It will thus be seen that although the different forms disclosed are somewhat different in their operations, they alt-work i, the side porupon the same principle, the sleeve holding the lens against rotary movement and the sleeve being connected with the shell rim to *aold the shell rim in place.

hr the form shown in Figs 12 and 13, the fastener is formed from a blank having a rectangular body 25, having stems 26 extending from its ends. The body of the blank will be bent to form the sleeve 27 which will be similarto the sleeve 9 and the stems 26 will be brought together to form a pin 28 corresponding to the pin 10. This pin willbe passed through the opening in the shell rim and a rivet head fdimcd to hold the shell rim in place.

' I claim:

A pair of eye-glasses includinga lens holding rim, a non-metallic rim positioned about the lens holding rim, sleeves carried by the lens holding rim and passing through cutouts formed in a lens to hold the lens against rotation in the lens holding rim, and means connecting the sleeve with the nonmetallie rim to hold the shell rim in place.
